Ask HN: What app or site you check first?

At first I only browsed /g/ om 4chan. They were a big fan of bitcoin back then but I ignored it since it's minor opiniot on minor internet forum. But after it reaching over thousands dollars I realized checking those internet forums amd keeping note could earm me a lot of money.

Now I check a few hundreds of subreddits and 12 4chan boards, almost every articles on hacker news&medium and summarize them on my diary every night.

Now I'm planning to learn Chinese to check Chinese websites.
